A method of detection of codes in a plurality of spectra of light, the method comprising: detecting, by a sensor configured to detect a first portion of the spectrum of light, a first region and a second region of an object, the first region and the second region having a first transmissivity property corresponding to the first portion of a spectrum of light and a second portion of the spectrum of light; and decoding, by a processor, a first encoding defined by the first region and the second region, the first encoding corresponding to a first machine-readable code visible in the first portion of the spectrum of light and invisible in the second portion of the spectrum of light; and identifying, by the processor, the first encoding during movement of a vehicle including the sensor through a physical environment.
10. The method of claim 9, further comprising: detecting, by the sensor configured to detect the second portion of the spectrum of light, a third region and a fourth region of the object, the third region and the fourth region having a second transmissivity property corresponding to the first portion of the spectrum of light and the second portion of the spectrum of light; and decoding, by the processor, a second encoding defined by the third region and the fourth region, the second encoding corresponding to a second machine-readable code visible in the second portion of the spectrum of light and invisible in the first portion of the spectrum of light.
11. The method of claim 10, further comprising: identifying, by the processor, the second encoding during movement of a vehicle including the sensor through a physical environment.
12. The method of claim 9, the first region and the second region comprising a first layer of the object and having a planar structure.
13. The method of claim 9, the third region and the fourth region comprising a second layer of the object and having a planar structure, and the second layer disposed over the first layer.
14. The method of claim 9, the first portion of the spectrum of light corresponding to an infrared spectrum of light, and the second portion of light corresponding to a visible spectrum of light.
15. The method of claim 9, the first transmissivity property corresponding to a first reflectivity in the first portion of the spectrum of light, and the second transmissivity property corresponding to a second reflectivity in the first portion of the spectrum of light lower than the first reflectivity.
16. The method of claim 9, the first region having a first brightness property in the first portion of the spectrum of light, and the second region having a second brightness in the first portion of the spectrum of light greater than the first brightness property.
17. The method of claim 9, the third region having a first brightness property in the second portion of the spectrum of light, and the fourth region having a second brightness in the second portion of the spectrum of light greater than the first brightness property.
18. A non-transitory computer readable medium including one or more instructions stored thereon and executable by a processor to: decode, by a processor, a first encoding defined by a first region and a second region of an object, the first encoding corresponding to a first machine-readable code visible in a first portion of a spectrum of light and invisible in the second portion of the spectrum of light; decode, by the processor, a second encoding defined by a third region and a fourth region of the object, the second encoding corresponding to a second machine-readable code visible in the second portion of the spectrum of light and invisible in the first portion of the spectrum of light; obtain, by a sensor configured to detect the first portion of the spectrum of light, the first encoding, the first region and the second region having a first transmissivity property corresponding to the first portion of a spectrum of light and a second portion of the spectrum of light; and obtain, by the sensor configured to detect the second portion of the spectrum of light, the second encoding, the third region and the fourth region having a second transmissivity property corresponding to the first portion of the spectrum of light and the second portion of the spectrum of light.
